A driving system and a display panel are provided. The driving system includes a timing controller and a driving chip. The driving chip receives the video signal and processes the video signal to output a characteristic current or a regular current to the display panel. The driving chip outputs the characteristic current to the display panel when the driving chip receives the characteristic video signal and to output the regular current to the display panel when the driving chip receives the regular video signal, and the characteristic current is smaller than regular current. The driving system of the display panel according to the present disclosure could alleviate the capacitor coupling effect caused by the large voltage jump introduced by the huge gray value difference when the display panel in a frame transition and thus improve the horizontal crosstalk of the display panel.
Legal claims defining the scope of protection, as filed with the USPTO.
6. The driving system of claim 5, wherein a driving capability of the first current source is smaller than a driving capability of the second current source.
7. The driving system of claim 1 wherein when the characteristic current is outputted to the display panel, the data voltage of the display panel is switched within 100 ns-300 ns.
8. The driving system of claim 1 wherein when the regular current is outputted to the display panel, the data voltage of the display panel is switched within 40 ns-60 ns.
9. The driving system of claim 1, wherein the characteristic video signal is a video signal outputted in a transition of an Nth frame and an (N+1)th frame when a gray value difference between the Nth frame and the (N+1)th frame is greater than or equal to 32, and N is an integer greater than or equal to 1.
10. The driving system of claim 9, wherein the characteristic video signal is a video signal outputted in the transition of the Nth frame and the (N+1)th frame when the Nth frame has a gray value of 32 and the (N+1)th frame has a gray value of 64.
11. The driving system of claim 9, wherein the characteristic video signal is a video signal outputted in the transition of the Nth frame and the (N+1)th frame when the Nth frame has a gray value of 64 and the (N+1)th frame has a gray value of 128.
12. The driving system of claim 9, wherein the characteristic video signal is a video signal outputted in the transition of the Nth frame and the (N+1)th frame when the Nth frame has a gray value of 64 and the (N+1)th frame has a gray value of 255.
13. The driving system of claim 9, wherein the characteristic video signal is a video signal outputted in the transition of the Nth frame and the (N+1)th frame when the Nth frame has a gray value of 128 and the (N+1)th frame has a gray value of 255.
14. The driving system of claim 1, wherein the timing controller is further configured to determine whether the display screen switching gray value difference is greater than or equal to 32.
